"LEWIS MOORE, OF 4JOLET, ILLINOIS, AssIGNOR To MOORE BROTHERS COMPANY, or

.IOL'IRR ILLINoIs;'A OOREORATION OF ILLINOIS.

STOVE,

To all whom it may concern:

Beit known that I, Lewis' MOORE, acitii zen of the United States, and a 'resident of- Joliet, i-iithe county of Will and State of, Illinois, hare rinvented certain'new and useful liniproveinentsin Stoves, of which the While attempts have heretofore been made to construct oven doors of this type, so far as l. ani aware, in such former attempts large single panes or plates of thick, heavy glass 'have been used and have. all resulted unsuccessfully, due to warpingg, or distortion lof the panes iii manufacture, whereby internal stresses aiedeveloped therein when said, panes arensecured iii-the yrigid frainesffornied in the oveii doors .to receive them, aiid to the excessive expansion and contraction of said panes in use, arising` from the high degree otl heat in wide ra-nge .of temperature y'to which they are subjected. which causes, pai'- ticularly when cooperating, soon result 1n. .the breaking ot said panes.

The primary object of the presentinven--- tion'is tooverconie th1s very objectionableA feature. which .P have discoveredV canr be Kdone in.y a'siniple andv etfective manner by the use of windows.comprisingr a plurallty Ot' small ianes o1 glass which are distorted very little.;if .at `all= lin manufacture and which' expand and contract independently,

so. that each panewill be unaffected by the v panes. .40,

expansion and contraction of'- the other ln. this inanner the internal stresses vdeveloped in said panes are too slight' tov break the glassr X further object of the invention isgto provide a simple frameworkfor connecting' thev adjacent edgesof lthe diiiereiit panes,

.which will hold said panes loosely, thus per- .niitting the use. of panes aggregating less, in width than the width of the continuous.. frame opening. in the door in which they are secured, thereby providing for free eXpan` sion yand contractioirof said panes, said,

i frame members being` so constructed, also,

that they will close spaces which' might VSpecification of Letters Patent.

' Otherwise be formed between the adjacent edges of the diferent panes. V

A further feature of the invention relates particularly to ovenA doors which are pivoted at their lower edgesand areadapted to forni` shelves for supporting utensils and dishes skids lwliich'extend slightly above the inner 'when placing. themY intolaiid withdrawing' them from the stove ovens. As 'inyinvention relates to this feature, the object of the invention is to provide bearing surfaces orl coniing into direct Contact .With the glass,

thus insuring` against scratching and v.niar- .ringof the glass.v

. To effecttliese several objects my inven# tion consists of the variousfeatures and details of construction hereinafter described.

and 'claimed. l. In thel accompanying drawing, in which my invention is fully illustrated-Figure 1 is a front view vof the outside. ofan oven .door embodying my invention. Fig 2 -is a partialxviewv of the'inner side thereof, part of the lining' plate being broken away toexpose parts .covered thereby'. Fig?) `is an en. arged sectional view on the line 3--3 of Fig 1. Fig. 4 is an enlarged'sectional View on tie line 4 4 of Fig. l1. Fig. .5 is an,` enlarged sectional View on the line 5-5 of Fig. 1; and Fig. G is a longitudinal-sectional' -view of one of thefraine 1nenibers`whieh connect the edges of adjacent panes or plates of lass.'4 h

veferring now. to the drawings, A. designates, as a whole, an oven door which, as regards it's'genera'l features, is of familiar construction, Acomprising the door proper l,

"said door. The position of said lining is deiined by lugs 3 on Athe door proper 1 on which said lining rests, and said lining is secured .to t-liedoor. proper byl bolts '4, saidplugs 3 .preferably 'comprising' lugs 4located closelyadjacent tothe bolts l and' to the edges of the recesslin the rear: side of saidl doorv proper. y As shown, also, said door is of the type vthe lower edge of which is adapted to pivotally connected to the bodyportion of the stovek so that it may be turned outwardly and downwardly into horizontal position to form a, shelf for supporting utensils and dishes whenbeing inserted' into and withdrawn from the oven. To provide` for thus supporting'said door A it' is provided at its lower corners with lugs 5, adapted to lengage corresponding bearings, not shown, .on the body portion of the stove', in a familiar manner.

Formed in the door A and comprising corresponding openings in the door proper 1 and in thelining 2, isa continuous opening 6 which is closed by a Window comprising two or more separate panes or plates of glass 7, a

desirable sizev for said panes or plates 7 Lbeing about/8 inches long by 5 inches Wide.

To effect the objects of myin'vention as itV relates to relieving the panes orvplates 'of glass 7 from all stresses due to distortion or warping of said panes or plates in manufacture and expansion and Vcontraction thereof in use, incident to securing the-same rigidly in the opening 6, I secure'said panes or `plates 7 in' position inl the following man- Aner:-Formed around ,the opening 6 in 'the-4 door proper 1 is a rabbet -8-Which is adapted to receive the panes or` lates of-gla'ss 7, said panes or plates' of g ass being secured in said rabbet by the overlapping edges of the lining 2 when secured -to the door proper 1,'5 the edges of said lining around the hole or opening .therein being preferablybentv down slightlyto fornil a short lip 9,' the relation being such thatwhen said -lining issecuredv in position, thene will be a slightclearance between'the end 4of said lip and the surface of the panes or plates of glass, see particularly Fig. 4. The adjacent edges of the panes 0r plates Tate' confined in grooves -10 formed in .frame members: 11,'

which extend .acrossthe opening 6l in the door A., the ends of which are secured in the rabbetS of the liningQ at opposite sides of said.' opening 6, the thickness of` said frame members beingsuch,however, that the ends thereof will be firmly -clamped in said rabbet 8 bythe lining 2, see particularly Fig. 5, thus permitting only very limited movementV of the plates or panes ,7. The grooves 10 are made slightly wider than the thickness -of the panes-or plates7 and the webs 12 of said frame ymembers are made suiiiciently strong-and rigid 4to prevent ycompression thereof under their designed conditions of use ,fthus insuring that thesides o'fjthe.- grooves 10wil1' not be rigidly clamped' uponthe. edges `ofsaidpanes or plates. -To pro vide'a tight joint between the sides of the grofwes o'r channels 1,10 andthe plates or 4getlier with their We panes of glass r' and'to prevent rattling of said plates or panes .in the grooves 10the sides of the grooves 1.0 are ieferably compressed together slightly at t eir outer ends,

so that they will have slight frictional en -v gagementjwith thesides of said plates orl panes, -the sides of said grooves being made suiciently thin, however, to render them j easily expansible.l

-The frame' members 11, in which are formed the' grooves 10 whichl receive adjacent edges of adjacent panes or plates 7, lare preferably connected together to form in effect av unitary structure. Said frame mem` bers will thus operate 4to confine said panes or platesand to limit the movfnent thereof as desired and will alsofoperate to connect 'adjacent panes or plates and to form a prac- .dleof said piece or strip andthe web portion bent backupon itself to bring'the webs of different sectionsinto contact and the outer ends thereof secured together, as by a tongue 13 forming an extension at-thefree end of the web -of one of said ,sections which is bent 'over the vweb Aof the other section, all asl clearly shown in Fig. 6 ofthe drawing.

Suitable acking,'as strips `110i asbestos, are prefer4 ly inserted inthe rabbet 8 to provide a tight jointaround the edges of said window. Beneath the 'ends of the framemembers 11, however, saidp'acking is broken away, as shown at 15, F ig'. 3,thus" ermitting saidv frameV members 4to bear against the shoulder forming' one side of said rabbet 8.

W ith the described constructiom'it is obvious that the panes or plates 7 will be 'supported -so as to' be freely movable within a4 ivory limited range and that practicall 'tigh ges o joints will 4be 'formed rbetween .the e adjacent plates and 'that rattlin` o said wing panes or plates will be' prevente to their shape, also, `the frame'members 11 arevery Istiff, so that they will sustain the .Weight of utensils and dishes resting on the sur ace of the doorA, when in lowered'posi tion, thus relieving the,.panes or plates? frm all-strain ldue thereto.l Also, such uten-` sils anddishes will rest directly upon the flanges of said frame members 11, ich ex- -tend above the surfaces of said plates or panes 7, thus preventing contact of said 'rectly utensils and tools with the surfaces of the glass, whereby scratching of the' glass Will be prevented as utensils and dishes are slidI being' also provided vwith 'a rabbet around'.
